ZFOC use special spun device successfully controlled the value of PMD,and make sure that it
keeps stable in cabling.

Interference pattern of spun fiber PMD measurement

Interference pattern of unspun fiber PMD measurement

In cabling,the capability of spun fiber is more stable than
unspun fiber,and the value of PMD is smaller.

z PERFECT CONNECTION CAPABILITY
Approved by optical communication products ministry of quality supervision and ipspection
center,the connection between ZFOC fiber in and outside is good .The single-end connect-loss
wont be over 0.1 dB and the double-end connect-loss is all little than 0.05dB.
